Write custom PayPal library - open&close balance,withdraw API

I need custom PayPal API in Java to provide functionality which isn't provided by PayPal original SDK: - ability to withdraw money to already defined bank account, - ability to open balance, - ability to close balance, - ability to move some amount of money between two balances. SDK from PayPal does not provide this functionality so you will need to revert to web scrapping. The library will need to log in using provided credentials, make sure that login has been successful (and potentially solve CAPTCHA request using library that does not use remote services) and execute necessary web requests. Here's detailed doc with API I expect: [login to view URL]
